"Microsoft gained nearly five percent market share in the Web server market, however still lags well behind market leader Apache, research and security firm Netcraft said Friday. Nonetheless, it was the biggest one-month swing in the history of the industry. With more than 80 million Web sites on the Internet, Microsoft now claims a 25.2 percent share, up 4.7 percent from March. Apache still leads by a wide margin, however it was down close to 6 percent to 62.7 percent. Sun remained a distant third, down slightly to 2.36 percent."

After having administered both Apache and IIS, I must say that it would be pure insanity to run IIS. It has more bugs than a town slut. Not to mention just about every time there is a security update, the whole system needs a reboot.

IIS may be ok in a single server set up, but in a cluster, you've just got a cluster **** waiting to happen.

Easy example, you have a cluster of three IIS servers running. Suddenly one hangs. Instead of reporting that it has hung, and then the cluster dropping it as it should until the administrator can restart it, IIS will just keep hanging until it completely makes your website unavailable. Yes, even if the other two are running fine, one of them will take it down. Kind of defeats one of the main reasons of a cluster, doesn't it?

Pure insanity? If you're running asp.net applications, it's your only choice. Also, if you're running an IIS cluster, you should definitely be running Application Center on top of that...alleviates all the issues you just mentioned. A recent gig I worked had a 4x4 cluster, and each month we had > 99% uptime with IIS6.

As far as bugs in IIS6, there have been virtually none, which is a lot better than can be said for it's predecessor. That being said, anyone still running IIS5 is definitely insane ;-).

Dude, have you EVER worked on AC2KSP2 before? Do you know how much WORK it is to keep it running at 99%?

And, just to let you know, it is WEAK when it comes to detecting hung IIS systems. Considering that I've been administering 3x3 AC2KSP2 clusters for well over 3 years now. Woah, the trifecta.... Not to mention the botched PerfDLLs it causes when "it feels like it".

Now, all is not a crap-fest with AC2KSP2. When it does work, it works like a CHAMP. Content Management is pretty easy, managing servers via the GUI is pretty sweet, Health monitors are helpful and the CLI is damm friendly to a *nix aficionado like myself.

Granted, AC2000SP2 is much more stable, MS support for it is next to nothing. The only support I've seen is from some MS dude called "George Chen". He seems to be THE ONLY DUDE supporting that beast.

Now, with 2K3, NLB is MUCH, MUCH nicer. And I do agree with a previous poster, you are Nucking Futs if you're running on IIS5.

While I'm ranting.... anyone heard on the newer version of AC? Just wondering...
